The Internet of Things: Edge Connect product allows connected users and devices to communicate on a publish-subscribe basis within reserved namespaces. In conjunction with dcp_auth_variable_extractor, this behavior affects how clients can authenticate themselves to edge servers, and which groups within namespaces are authorized to access topics. It transforms a source string value extracted from the client certificate and stored as a variable, then generates a hash value based on the selected algorithm, for use in authenticating the client request.

Note that you can apply this hash transformation, or either of the dcp_auth_regex_transformation or dcp_auth_substring_transformation behaviors.
